I prefer #1, but would like it even more if you made it more unbalanced. For example, if the 2 dark bands fell in different areas rather than directly across from one another. I think it would look more intentional that way. You could even keep it balanced but opposite if you put one dark band perhaps 1/3 of the way down from the top and the other 1/3 of the way up from the bottom.
Or you could have more bands on one side, of different widths. Perhaps 2 on one side and 3 on the other; some narrow and some wider.
Your quilt is going to be awesome, no matter how you end up finishing it, I think it's wonderful now!!!
